. To all whom it may concern."

the following is a specification, the principle of the invention being herein explalned and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The object of the present. invention is a signal lamp particularly fitted for use on automobiles and motor boats where it is desirable tohave a single lamp which will project a beam of light of diflerent colors.

In the present lamp 1 have designed an inexpensive lamp which is adapted to project light of several colors, and I have also provided means for changing the colors so that the lamp may be a rather small searchlight with provision for quickly shifting where a colored beam is desirable, as for use in signaling. or as the side light on a motor boat. To the accomplishment of the foregoing and related ends, said invention, then,

. .consists of the means hereinafter fully described and particularly pointed out in the claims. I a 30 ,The annexed drawing and the following description set forth in detail certain mechanism embodying the inventlon, such disclosed means constituting, however, but one of various 'mechanlcal forms 1n WhlCh the principle of the invention maybe used.

Insaid-annexed drawing: 1 Figure 1 is a longitudinal section through the lamp; and Fig. 2 is a section taken on the line 2-2, Fig. 1.

The present lamp consists of the usual outer casing or shell 1 of any desired form, except thatit is open at both ends, said cas ing having its front end closed by a glass lens 2 mounted'therein in the usual way and having its rear end closedby a separable plate 4 that is normally held in place by screws 15,:or other'suitable-means. A reflector 3 is held in the casing, said reflector being of general annular form, having a central aperture 5 therein, through which the lamp bulb 8, or other lighting element, supported as hereinafter described, projects ,fr'om the rear, so as to occupy a proper positionfiwithrespectto said reflector.

lamp bulb, but also carries the other parts of the lamp which are features of present interest, all these parts being removable with the plate, so that if it is necessary to replace or repair any such portion, this may be readily accomplished.

One of the parts thus carried by said plate 4 is the reflector center 16, which is of the same curvature as the main reflector 3, but,

is a trifle smaller in diameter than the aperture 5 therein, so as to leave an annular space for the purpose presently to be. described. This reflector center is attached to the plate 4 by means of strips, or fingers 6, and serves in turn to support a lampsocket 7 of any desired type in which the bulb 8 is mounted. A switch 9, rotatably mounted in the plate 4, isinterposed in one of the leads 17, that form the lamp circuit, so as to serve to turn the lamp 8 on or ofl', as desired.

From the foregoing, it will be seen that both the lamp and the switchycontrolling the same are carried by the detachable plate 4, so as to be removable therewith from the casing l, such'removal being further facilitated by having the leads 17 pass throu h an'opening 19 in theplate instead of in the casing.

In addition to the switch 9, worm screws :85. 10, two in number as shown are rotatably' mounted in this same plate 4, and these are provided with knurled heads 11 or other.

equally convenient means for operating the same.' As here. shown, two transparent. colored sleeves 12 and 13 are concentrically mounted around the socket 7 so as to be capable of longitudinal movement axially.

of said socket, each such sleeve having a threaded nut attached thereto and adapted to receive one of the worm screws 10. As illustrated in-Fig. 1, one of these sleeves 12 is 1 through the annular space between the two reflector-portions 3 and 16 and laterally sur-- rounds the bulb 8, and in this position all the light rays must obviously pass through the sleeve before striking the main reflector portion 3. u the central portion 16 of the reflector will in its extended position, in which it projects I Such rays, however, as strike be directed, in the main, as a clear beam of light, so that the result will be "a broad an nular beam of colored light surrounding a central vbeamor core of white light. It will be understood that a single sleeve will be 5 I of the vehicle stil with a very steep pitch so that only" a few use as a side often used of a. single color-(as red), and:

where two are employed, one will be red and one green, or they may be other colors depending on the use to which the lamp is to be put.

The Worm screws 10 are preferably formed turns are required to move a sleeve from its extended to itsretracted position. The two knurled beads of the screws and the switch button willbe so arranged as to ,be readilygrasped and distinguished from each other.

The sleeves iwill be formed of any suitable transparent material such as glass, celluloid 'or mica, and as they are removably mounted with the rear plate they can be replaced or changed very easily. Such a lamp is particularly suitable for a colored light is needed, as it can be=taken ;oif and used for ordinary lighting purposes.

For use on automobiles, as a searchlight and ghton a motor boat where v as a danger signal when one of the colored sleeves is used, the present device-presents a-number of advantages. At the same time.

.it is inexpensiveto manufacture and. in case the lamp bulb requires to be changed after the lamp is installed, by simply removing the plate, not only is-sueh bulb rendered directly accessible, but the wiring connec-' tions and other operative parts as Well. By

reason of the fact that a portion fthere- 'flec'ted-li'ght, even when the colo'redtrans mains unaffected by or, for other purposes, the illuminative efi'ect".
